How Can Delo 15w-40 Dino oil be better than Syn?

Possible, Rotella is a low grade Group III syn and Delo is about the best Dino. Without seeing the UOA's it's hard to comment more than that.
You must be refering to me.
Here are three consecutive 8k mile UOAs with Mobil 1 Truck & SUV, Rotella Syn, & Delo CI-4+.
Aluminum: 3, 3, 2
Chromium: 1, 1, 1
Iron: 13, 10, 4
Copper: 5, 3, 2
Lead: 2, 2, 2
Tin: 0, 4, 0
Mileage on my Duramax ranged from 60k to 85k+, so the engine was well broken in. The M1 was put in in the winter sometime, so that probably accounts for the higher wear numbers. Basically, synthetic doesn't help my wear numbers, & I don't tow heavy very often, so I don't waste my money on synthetics.
Most of my UOAs are already posted in the UOA section.

CHEVRON Delo 400 has Isosyn tech in it. From reading posts here...and I have used it for years in my Largecars (Rigs)...it is considered by the Courts (yes, you read this right) to be a synthetic or group III....Why?....because it performs as good as synthetics and Chevron proved it in court...or was that Mobil?....beside all the ubalubbbbba.
Chevron Delo is a fine...very good oil and you can purchase it for a buckfifty a Qt. Truckers have been convinced for decades. Plus, Chevron Corp. is customer friendly, puts $$$$'s back into there products, does not hide facts, and does extensive development of additives (Orinite Corp.)

Chevron Delo400's Isosyn oil is NOT group.III. It is a group.II+
Group.II+ It is very close to reaching group group.III but it falls short in mostly viscosity index.

First off, Delo 400 is an excellent oil.
Secondly, with all due respect, one UOA on one oil compared to one UOA on another oil in the same engine isn't worth squat.
If you listen to anyone that has been using UOA's to analyise their engine fleets, they perform multiple UOA's to establish trends so they can more predictably compare results.
A one off UOA really doesn't mean much.

I have used Blackstone labs for the last 3 years and have spoken to several of their techs about oils after having analysis's done on two of my Duramax's. I was told straight out by most of them that Synthetics are all hype and waste of money from the data they have logged. They even went so far as to tell me they see higher bearing wear numbers on Powerstrokes with synthetics and they don't know why. One tech told me everyone there uses dino in their motors. I used to be a firm believer in synthetics but, that got me back to dino. Bye the way Blackstone consideres Delo the best of the dino's. It's your money!

tdi-rick,
"With all due respect", that's why I said that most of my UOAs are already posted in the diesel UOA section. After a dozen UOAs on my Duramax, Delo consistently gives me better results than either Rotella "syn" or M1 T&S. There isn't a big difference in the numbers, but they're always better with Delo.

I have found delo to be great oil, but MPG suffered in my MB OM 617 and OM603 engines, compared to T&SUV/delvac 1, even when mixed 50/50 with delvac 1300s.
Perhaps that will change with the moly that is in the oil now???

Just a tip for the hardcore Delo users, AutoZone has SAE 30 weight for $.99c a GALLON. You have to jump through some hoops, but I got 70 gallons for $70. Check the "Specials" Forum. Looking forward to it in the Euro cars I service for 3-seasons and mid-summer in the Asian cars.
There are lots of variables, but bottom line is Delo is an outstanding oil. It has a robust additive package and holds up for extended periods of time. Analisis is normally used to establish trends and maintenance cycles, but can and is also used to determine differences in oils.
I have some samples posted on my site where the viscosity at 100 to 150 hours was way below what it should be, thickening up by 200 to 250. Most oils do not do that.
But also, in reality it is about the third sample that give a true rating. You can put a lousy oil in an engine and not see the wear metals in the analisis when they stick to the walls of the engine and pan as sludge. Then put a good oil in and onder why the wear numbers and solids are high.

Yeah, widman is right! That is why Cummins does not recommend to use UOA's alone to determine your OCI. Cummins says that wear metals can hide in sludge, deposits etc. I'm not knocking Delo, its reputation is good. Compared to most synthetics, it is cost efficient at normal OCI's.
Rotella 15w/40 is a gp II type of oil .Delo has a better add package and base oil .
Agrees with Steve!
Now with the extra moly, really adds to the robust.
